Speccaton of Letters Patent. Application iiled Tuly 10,1905. Serial No. 268,958.

Patented 'May 29, 1906.

To a/ZZ whom it 771/013/ concern,.-

Be it known that I, HENRY F. ROONEY, of Randolph, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Vibrators, of which the following is a specification.

This invention relates to means for imparting rapid vibratory motion to the applicator of a massage apparatus by thel action of a sliding device on a rod carrying the applicator, the said device being adapted to alternately gri and release the rod in rapid succession w en moved lengthwise thereon, and thus impart to the rod and to the lapplicator thereon a series of vibrations.

The invention has for its object, first, to provide certain improvements relating to the sliding device or rod-vibrating slide, whereby its efficiency is increased, and, secondly, to provide the rod with means for increasing the amplitude of the vibrations imparted to it by the slide.

To these ends the invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specnication, Figure 1 represents an edge view of a vibrator embodying my invention. Eig. 2 represents a top plan view of the same. Fig. 3 represents a section on line 3 3 of Fig. 2.

The same reference characters indicate the same parts in all the figures.

12 represents a metal rod whichis preferably cylindrical and is preferably made of steel, although any other suitable metal may be used.

13 13 represent knobs or rounded enlargements at the ends of the rod, one of these serving as a handle and the other as an ap licator. The knobs may be alike, so -t at either may be used as an applicator.

With the rod 12 is engaged a rod-vibrating slide in which the chief portion of my invention is embodied. The said slide comprises a resilient hardened-steel strip bent to form arallel end portions or rod gripping and reeasing members 14 14 and a curved connecting portion 17. Each of the members 14 has an orifice 15, formed to surround the rod with a sliding fit. The intersection of the walls of the orifices with the sides of the members 14 forms angular jaws 16. When the members 14 are at right angles with the rod, they are adapted to slide freely thereon.; but when they are tipped or inclined slightly from a position at rig t angles with the rod the jaws 16 bite or engage the rod and oppose movement of the members 14 along the rod.

The slide has oppositely curved or inclined side portions 18 18, which constitute fingerrests, enabling the operator to'apply pressure to the slide in directions oblique to the rod, this pressure tending to tip the members 14 into rod-gripping relation with the rod.

In o erating the device the operator gras s one o the knobs in one hand, presses t e other knob as an applicator against the body to be treated, and pushes the slide along the rod by pressure of a finger or thumb against one or the other of the inclined rests 18, care being taken to press only the rest at the rear side of the slide. The pressure thus directly applied to the rear member 14 is yieldingly imparted through the spring to the forward member, which alternately grips and releases the rod independently of the other member. It will be seen, therefore, that each member 14 has an independent rod-vibrating action, so that the rod is vibrated with greater rapidity than would be possible if the members 14 were rigidly connected and compelled to o erate in unison. To the end portions of t e rod 12 are rigidly affixed arms 19, which are notched to engage the end portions of helical springs 20. These s rings extend parallel with the rod and are iheld extended and under tension by the arms with which their ends are engaged. I prefer to employ two springs, although one or any other desired number may be employed. The vibrations of the rod are communicated to the springs 20. The vibrations of the springs add to the vibrations imparted to the applicator by the rod.

I claim- 1. A vibrator comprising a rod having an applicator, and a slide having two rod gripping and releasing members separated by an intervening space, and each having an orifice the wall of which is in close sliding contact with the rod, and a spring connection between said members, whereby pressure applied to one member lengthwise of the rod is yieldingly communicated to the other mem- 2. A vibrator comprising a rod having an applicator, and a slide having two rod grip- IOO ping and releasing members separated by an intervening space and each having an orifice the Wall of which is in close sliding contact with the rod, and a resilient shank yieldingly 5 connecting said members, said shank having oppositely-inclined iinger-rests.

3. A vibrator comprising a rod having an applicator, a rod-vibrating slide movable on t e rod, and arms rigidly attached to the end Io portions of the rod, and one or more helical springs connected at their ends with the said arms and maintained under tension between the same, said springs being vibrated by the vibrations of the rod.

In testimony whereof I have aiiixed my 15 signature in presence of tWo Witnesses.
